The locally irreversible rearrangements of particles in
the glass are evaluated by the non-affine displacement
\(D_{\rm min}^2\)  introduced in Ref. [1]} and which is defined as the minimum of
\(D_i^2=\frac{1}{N_i}\sum _{j(i)}\left[\vec{r}_j(\gamma )-\vec{r}_i(\gamma )-{\bf F}_i\times (\vec{r}_j(\gamma -\Delta \gamma )-\vec{r}_i(\gamma -\Delta \gamma ))\right]^2,\)
